To all 'whom t may concern.'

Be it lmovn that I, LuoNAko Ban'rnefrr, a citizen oi the United States, residing Boston, in the county of Suiiolk and State of Massachusetts, have invented a. new and useful Rear Automobile Signal, of which the following is a Specification.

flhis invention relates to automobile signels, and has for its objectA to provide a signal device which can be mounted on the rear of an automobile in the manner 'to indicate to any observer the movement of an automobile.

The invention is illustrated in the accompenying drawing in vvhich- Fig, l, is a plan view, partly in' section, of a rear automobile signal constructed in accordance with .my invention;

Fig. 2, is an elevation thereof, partly in section; and,

Fig. 3, is a sectional view, on the line 3-3 of Fig. l.

in the drawing, like numerals of rei erenoe refer to the same parts in each of 'the views.

In practice provide a central casing 4, provided `with inturned ends 5 and 6, and having mounted therein e frame 7, provided with screw holes whereby a central screw 8 may be used to hold the frame Withinthe casing, and two end screws 9 may be used in connection with discs l0 to clamp the end casings 11 and 12 in positionthe inturned ends 5 and 6 being used in this connection, as will be readily understood.

The central casing has mounted therein an electric bulb 13, visible through a glass 1li, which is preferably red, and through a ,glass 15 in the bottom of the casing, which 1s preferably White.' The lass 15 may be mounted in a door 16, whic ymay be swung down, as shown in dotted lines in Figure 2, to give ready access to the bulb 13, and to the electrical connections 17, of the electric bulbs 18 mounted in each of the end casings, 1

and Wired to give the signals desired.

Each of the end casings is substantially round in cross-Section; and each is provided with an angled, perforated portion 19, in

the front thereof in which is mounted in a visible manner a glass 20 on which the signal may be deined by a perforated mask 2l, held in place with a spring ciainp having angled ends 23 and 24, vwhich are oppositely disposed, as clearly shown in Fi ure l.

r s shown in the drawing, the masia 2i is perforated to define :in arrow on. the glass 20; but it is evident any indicatingdevice could be produced that might be stamped in the mask.

In operation, the bulb i3 is supposed to be lighted at all times` when the automobile is in operation at night; and furnishes the tail light and the illumination, for the license tag. The bulbs 'i8 are. illuminated 'only when it is desired to turn to the right, or to the leftr la? both are illuminated at once it is an indication that the automobile is about to stop;

lt is desirable that the glasses 20 be ci ground, red glass as the arrow would be so sharply defined on the same in connection with the mask as to be plainly visible in daylight. Thus the signal would be available for use both in the day time and at night.

it will thus be seen that l have provided a rear signal that is easy to construct, easy to assemble, and eticient in use.

The drawings show that the end casings have cut out 'portions so the same can he readily passed Within the central casing; and will not interfere 'with the radiation ci the light when in useD v I claim:

l. A rear signalii'or, automobiles comprising a central casingprovided with means for access to the interior thereof, a, tail light mounted in said central casing, two end casings in said central casing, and clamping means securing,y said, easings in* place, each of said end casings projecting Within said central casing, and having eut-out portions adapted to coact with the clamping means, and each having1 a signal device mounted therein, for the purpose set forth.

' 2. The herein. described rear automobile signal comprising a central casing with irf turned ends, a, frame mounted in said casing and provided with discs at, each end thereof and with an electric bulb centrally thereof forming a tail light, said casing being pro- 5 vided'with two ports closed with glasses, and end.cases mounted in the opposite ends of said central casing and clamped therein in connection with said discs and inturned ends, each of said end casings having a cutout portion, and carrying an electric bulb, a 10 glass, a perforated mask, and a spring clamp, for the purpose sei'J forth. Dated April 16th, 1920.
